3 Sheets-Sheet 2 INVENTOR Jaw-m MB. J7 VAPeS-B Patented Aug. 10, 1971 3 Sheets-Sheet 3 This invention concerns carding engines.

It is an object of the present invention to provide means to ensure that the bends of a carding engine retain parallelism and concentricity and proper spaced relationship with respect to the ends of the cylinder despite any movements of the main frame of the carding engine which might occur.

According to the present invention a carding engine is characterized in that the bearing blocks for the axle ends of the main cylinder are mounted on the frame of the carding engine in a manner which permits swiveling movement thereof at least about the longitudinal and vertical axes with respect to said frame, said axle ends being carried nonswivelably by said bearing blocks, and the bends of the carding engine being rigidly secured to said bearing blocks.

The invention will be further apparent from the following description with reference to the figures of the accompanying drawings, which show, by way of example only one form of carding engine embodying the invention.

OF THE DRAWINGS:

FIG. 1 shows a fragmentary side elevation ofthe carding engine;

FIG. 2 shows a cross section of the carding engine on the line 11-" of FIG. 1 a

FIG. 3 is a view corresponding to FIG. 2 of a modification;

FIG. 4 is a view similar to FIG. 2 of a further modification; and

FIG. 5 is a fragmentary view of the other end of the axle from that of FIG. 4.

Referring now to the drawing it will be seen that the method of mounting the axle end of the main cylinder and the bend at one side of the carding engine, only is shown, and it should be understood that the arrangements provided on the other side of the card are identical.

The main cylinder has axle ends 11 which are mounted nonswivelably in bearing blocks 12 by means of axially spaced bearings 13 and 14 to ensure that the ends of the cylinder 10 retain parallelism with the inner faces of the bearing blocks 12, and at least at one side to restrain the cylinder against axial movement relative to the bearing block. Bolts 12a fix bearing block 12 to the bends.

The bearing blocks 12 are seated on base blocks 15 and are swivelable about vertical axes relative to the blocks 15 on stub axles 16 extending through blind bores 17 and 18 in the bases of the blocks 12 and upper faces of the blocks 15 respectively.

The base blocks 15 are mounted for swiveling movement about their horizontal longitudinal axes and for this purpose are rotatably mounted on shafts 19 whose ends are located in bores in mounting blocks 20.

The mounting blocks 20 are rigidly secured to longitudinal side frame members 21 of the carding engine.

The bends 22 of the carding engine (and possibly other parts) are secured rigidly to the bearing blocks 12.

It will be appreciated that movements of the frame members 21 will not disturb the setting of the bends 22 with respect to the cylinder 10 since the bends and cylinder are compelled to move together. It is of course necessary to provide for movement of the bearing blocks 12 relative to the frame members 21 to prevent stressing of any parts of the assembly. Shims 220 are provided between the bends and the bearing housing 12 to enable the relative position of the bends and the cylinder to be accurately set.

It will be appreciated that it is not intended to limit the invention to the above example only, many variations, such as might readily occur to one skilled in the art, being possible, without departing from the scope thereof.

As shown in FIG. 3, wherein like parts to those of FIG. 1 and FIG. 2 are given like reference numerals, it can be seen that the bends 22 are provided with bearing block 12a at the inner end of which is mounted a bearing 13. At the outer end of the block 12a is a bearing housing 24 and between this housing and the block 12a is located a shim or shims 220 which serve to enable the position of the bends relative to the cylinder 10 to be accurately defined. The bearing housing is secured to the end of the block 12a by bolts 23 and bearing 14 is fixed to axle end 11.

In FIGS. 4 and 5 it can be seen that the arrangement is similar to FIG. 3 in that there is provided a block on the bends and in that shims 22a and bearing housing 24 are provided at the outer end of the block 120. In this case also, the bearing 14 is fixed to axle end 11. The block 12a is provided with diametrically opposed part spherical seatings 26 which are located in housing 25 directly attached to the carding engine frame 21. A locating pin 16a is provided in one seating to prevent axial movement. Pin 16a fits loosely in hole 16b in seating 26 at one end of axle 11 (see FIG. 4) and tightly in hole 16b in seating 26 at the other end of axle 11 (see FIG. 5).
